I am heading home from an outstanding Infection Prevention 2017. There was a fair bit of discussion about hospital-associated pneumonia (HAP). HAP does not get the attention it deserves and there is more that we can and should be doing to prevent it. Although, we need to keep an eye out for unintended consequences in tackling HAP.
We’ll be publishing the results of the vote on whether or not we can halve HA-GNBSI by 2021 later this week. Right now, it looks like Martin is heading for a comfortable, if somewhat depressing victory (“No, we can’t halve GNBSI by 2021”) but there’s still time to ride a wave of positivity and vote with me that “Yes, we can halve GNBSI by 2021”. So, I thought that now would be an appropriate time to review the recent JHI paper that both Martin and I referred to, providing some enhanced epidemiological data on E. coli BSIs in England.
We have blogged before how CAUTI is rather ‘unloved’ as an HCAI prevention target. CLABSI reduction, on the other hand, is all the rage. Now, there is a key reason why this makes sense: outcome! A CLABSI is much worse news for a patient than a CAUTI. However, this doesn’t mean we should turn a blind eye to CAUTI, especially since CAUTI is a common root cause for CLABSI! In the US there is an addiional driver for preventing CAUTI: the costs associated with CAUTI are no longer reimbursed by insurers (since 2008). With this in mind, it was great to see a CAUTI reduction study published in NEJM recently (and see some interesting analysis on the Controversies blog).
Dogs are recognised to have the keenest of noses and have been used for detecting illicit drugs, early stage cancer and even C. difficile including an outbreak (possibly a cheaper option than PCR for screening – I should have used this in my debate with Jon). Now a new study finds that trained dogs can reliably detect significant bacteriuria.
As we move inexorably towards the end of antibiotics, antibiotic-sparing approaches to the management of infectious diseases become more and more attractive. A study published recently in the BMJ compared the ‘symptomatic’ treatment of uncomplicated UTI in women in the community using ibuprofen with antibiotic treatment using fosfomycin.
So I’m really quite interested in seasonality of infections. I first became interested in it when looking at increases in E. coli bacteraemia for ARHAI (report here) because of Jennie Wilson’s excellent paper showing seasonality of gram negative bacteraemia, echoed by similar observations and conjecture on warmer weather, more infection. This is true in hospitals as well as the community. Why would this be? We have tussled with increasing E. coli bacteraemia in the UK for a few years now. Goes up every summer, does not return to the baseline, goes up again next summer etc., etc.. Other countries have also reported this. I have heard some suggest this is due to longer hours of daylight leading to more barbeques and more sexual activity. Given that the majority of infections in the UK are >70 years of age, my senior years have no fears for me then.
